Paulo Dybala hit a fifth-minute opener and Gonzalo Higuain added a quick second as Juventus humbled Lazio 2-0 on Sunday to restore their four-point lead over Roma.

Despite a poor record against the Turin giants in recent years, Lazio travelled to Turin looking to end the Serie A champions' 26-match unbeaten league run at home.

But Juve coach Massimiliano Allegri overcame a number of enforced absences to send out a reshuffled side that should have finished with a far more generous tally as several players spurned chances.

Juve's 16th win of the campaign leaves Allegri's men four points ahead of Roma, who can reduce the gap to a point with a win over Cagliari on Sunday.
